中文摘要:
      目的 为轴承设计和公差选用提供理论依据与指导,有效解决轴承精密公差的选用问题。方法 以高速糊盒机中6300型号的深沟球轴承为具体分析实例,建立深沟球轴承的数学模型,分析轴承参数微量变化带来的影响及其变化规律,并通过软件进行仿真分析与验证。结果 深沟球轴承的疲劳寿命、刚度与滚子数量、直径及其内外圈曲率半径有着密切联系,其中轴承疲劳寿命对滚子数量和滚子直径变化表现敏感,寿命的增加量达到77.78%,轴承径向刚度对轴承滚子数量的变化很敏感,刚度的增加量为23.08%,而轴承轴向刚度对滚子直径和套圈曲率半径的变化较为明显,刚度的增加量分别为38.29%和15.1%。结论 在一定范围内应尽量选取和设计滚子数量较多、直径较大、内外圈曲率半径较小的深沟球轴承,使其疲劳寿命与刚度性能达到最优。
英文摘要:
      The work aims to provide theoretical basis and guidance for the bearing design and tolerance selection, so as to effectively solve the problem regarding the selection of bearing precision tolerance. By taking 6300 deep groove ball bearing in the high-speed box pasting machine as a specific analytical example, a mathematical model of deep groove ball bearing was established, and the influences brought by micro variation of bearing parameters and their change law were analyzed. Moreover, the simulation analysis and verification concerned were conducted through software. The research showed that the fatigue life, stiffness, number of rollers and diameter of deep groove ball bearing and the curvature radii of its inner and outer rings were closely related to one another. The bearing fatigue life was sensitive to the change in the number of rollers and roller diameter, with the change of fatigue life up to 77.78%. Bearing radial stiffness was sensitive to the change in the number of bearing rollers, with the variation of 23.08%. However, bearing axial stiffness was more sensitive to the change in roller diameter and curvature radius of bearing ring, with the variations of respectively 38.29% and 15.1%. In a certain range, deep groove ball bearing with more rollers, larger diameter and smaller curvature radii of inner and outer rings should be preferably selected and designed, so as to achieve the optimal fatigue life and stiffness performance.
